Again I see what you mean but are you throwing them or are they falling because of over extension? Most people with a minimum of training in most martial arts are trained to not over extend so this may not work on all people.
IMHO, its relatively easy to get even trained people (except at rather high levels) to over extend.
So yes, I tend not to throw them but let them fall because of their own body momentum, mechanics, and alignment. Also because either their mind really wants to hit me or their mind really doesn't want to be hit by me.
